Being diagnosed

Sooo every year twice a year since getting off BC i have had 70 day cycles others are about 28/40 days. Went for a blood test and ultra sound, blood tests are all normal except I have extremely low iron and my ultrasound showed that I have 25 cysts on each ovary! Is that a lot or am I just over stressing about it. My gp has referred me to a specialist and I’m super nervous as I’ve never gone through anything like this. I’m 22, not TTC but want to loose weight and get my cycle back to normal. Looking to get some ideas of what my first appointment with my specialist would be like to ease the nerves.
